AbstractSulphur mustard, [bis (2-chloroethyl)] sulphide (SM), is a bifunctional alkylating agent. SM forms sulphonium ion in the body which alkylates DNA and several other macromolecules, and induces oxidative stress. Although several antidotes have been screened for the treatment of systemic toxicity of SM in experimental animals none of them are recommended so far. In the search for more effective and less toxic antidotes, various combinations were tried against SM induced toxicity and skin lesions. SM exposed through percutaneous route was used to evaluate the prophylactic efficacy of various combinations. Low dose of DRDE-07 (S-2(2-aminoethylamino) ethyl phenyl sulphide), DRDE-30 [S-2(2-aminoethyl amino) ethyl propyl sulphide], DRDE-35 [S-2(2-aminoethyl amino) ethyl butyl sulphide] with amifostine combinations, were given orally 30 min prior to SM exposure. Significant depletion was observed in body weight, organ body weight index and hepatic GSH and GSSG content in mice after SM exposure. Pretreatment with low dose of different combinations of DRDE-07, DRDE-30 and DRDE-35 with amifostine could recover biochemical alterations and histopathological changes caused by SM exposures.
